BACKGROUND: Self-expandable metallic stent is an effective method in palliative treatment of malignant biliary stricture. However, it is controvesial in benign biliary stricture due to recurrent jaundice, cholangtitis, and finally, obstruction of stent. The purpose of this study was to determine the long-term effectiveness of Gianturco expandable metallic stents in benign biliary strictures. METHODS: We inserted Gianturco self-expandable metallic stent in 13 patients (42~69 years old, 6 men and 7 women) with benign biliary stricture between November 1991 and September 1994 in Wonkwang University Hospital. All patients had a previous history of biliary surgery and underwent balloon dilatation procedure for management of strictures. Insertion routes were percutaneous transhepatic biliary drainage tracks in 8 cases and T-tube tracks in 5 cases. The insertion site was the right intrahepatic duct in 5 cases, the left intrahepatic duct in 2 cases, both intrahepatic ducts in 1 case, common hepatic duct in 1 case, and distal common bile ducts in 4 cases. The stents used were 2~6cm in length and 8~12mm in diameter. The follow-up period was 46months to 81months(mean, 67months). RESULTS: The initial technical success rate was 100% with good immediate patency in all patients. Nine patients(69.2%) had no recurrence of the initial strictures during the follow-up period and 4 patients(30.7%) had further symptoms of biliary obstruction caused by recurrent cholangitis or intrahepatic duct stone formation. These 4 recurrent biliary strictures were treated by surgical methods. The recurrent stricture sites were distal common bile duct(1case), left intrahepatic duct(1case), both intrahepatic ducts(1case), and Roux-en-Y hepaticojejunostomy site(1case). CONCLUSIONS: According to the results of long-term follow-up, expandable metallic stent is a useful method in recurrent biliary strictures, especially in the case where operation is not feasible; poor risk patients, patients refusing operation, multiple biliary operation.

PURPOSE: We reported the CT and MR findings of 2 cases with Sturge-Weber syndrome which were not accompanied by facial nevi. MATERIALS AND METHODS: They were examined with both CT and MR in one case and with MR only in the other case. RESULTS: CT was better than MR in the demonstration of the characteristic cortical calcification. MR was superior to CT in the depiction of the abnormalities of the surrounding parenchyma and the intense enhancement of pial angiomatosis with Gd-DTPA enhancement. CONCLUSION: Gd-DTPA enhanced MR imaging could be useful in the demonstration of the presence and extent of pial angiomatosis in patients with suspected Sturge-Weber syndrome.

The use of atypical antipsychotics is limited by occurrence of adverse reactions such as weight gain, despite of their benefits. This article provides a comprehensive review and discussion of the most significant findings regarding obesity-related pathways and integrates these with the known mechanism of atypical antipsychotic action. The focus of this article is primarily on the genetics of obesity related pathways that may be disrupted by atypical antipsychotics. This review also discussed weight gain, hyperglycemia or occurrence of diabetes while being treated with atypical antipsychotics from the point of view of pharmacogenetics. Pharmacogenetic research seeks to uncover genetic factors that will help clinicians identify the best treatment strategies for their patients. It will aid clinically in the prediction of response and side effects, such as antipsychotic-induced weight gain, and minimize the current "trial and error" approach to prescribing in the near future. This article also presents the genetics of both central and peripheral pathways putatively involved in antipsychotic-induced weight gain while providing a comprehensive review of the obesity literature. This article also review obesity related candidate molecules which may be disrupted during atypical antipsychotic drug treatment.

OBJECT: The goal of this study was to examine the changes in body weight and glucose levels of the patients treated with risperidone, clozapine or haloperidol in order to compare the effect of risperidone or clozapine with that of haloperidol. METHODS: For nine months(January to September, 2003), a prospective study was performed in 60 patients with chronic schizophrenia who were in Seoul National Hospital. Two-week period was required for a drug wash-out. The patients were randomly assigned to risperidone, clozapine and haloperidol groups. They were given risperidone(n=20), clozapine(n=20) and haloperidol(n=20), respectively, everyday for 12 weeks. To examine the effects of these drugs on body weight and fasting glucose levels, we measured body weight and glucose levels of all the patients first without the drug treatment and at each end of 4, 8, and 12-week periods with the treatment. And we examined the differences among three groups in the changes of body weight and fasting glucose levels. RESULTS: There were no significant differences in the changes of the body weight and fasting glucose levels between the atypical antipsychotics(risperidone or clozapine) and the typical antipsychotics(haloperidol). CONCLUSION: The study in the patients with chronic schizophrenia suggests that risperidone or clozapine do not cause any additional effects on body weight or glucose levels compared to haloperidol.

The clinical evaluation was done in eighteen eyes of nine patients with bilateral BRVO in aspects of onset, visual acuity, interval between onset of one eye and the other, sex ratio, associated systemic diseases, location of the affected vein, the effect of macular edema on visual acuity and ocular complications. The onset of age was from fifty one to sixty eight years. Eight patients were women, and one patient was man. Hypertension was the most common associated systemic disease. Ten eyes (55.5%) of bilateral BRVO were affected the superior temporal branch vein, the sites of occlusion were not more than two disc diameters from the optic disc in fifteen eyes (83.3%). The complications of seevere visual loss had macular edema, macular capillary nonperfusion, retinal neovascularization and vitreous hemorrhage. Among of six numbers who could be followed up more than one year, and visual acuity of five eyes with macula edema were decreased than five other eyes developed one year or later. Eyes that were more than five disc diameters of capillary nonperfusion, as visualized with fluorescence angiography were thirteen (72.2%). Of these eyes, six (46.1 %) eyes occured retinal neovascularization, five of those had macular capillary nonperfusion. four of those were 0.1 in final vision. Three of four eyes with vitreous hemorrhage were very slowly improved in visual acuity, but another was decreasing in visual acuity due to other ocular complications We thought that woman with history of BRVO due to hypertension in sixth and seventh decades should be followed up the other eye for three years.

Building a database file in the medical literature using personal computer enables individualized computer user to search with a small amount of time and effort. We developed a computer program for searching medical literature. This program was developed with Clipper database language, and runs on IBM-PC-compatible computers. The data is based on the Index of Korean Journal of Urology which was revised in 1991. The program is focused on the function of retrieving and printing of keywords, authors and titles, etc. We expect more advanced and beneficial program for searching of medical literature based on this program.

Retinal hemorrhages in the newborn infant were first described shortly after the invention of the ophthalmoscope(Jaeger. 1961). Frequency of the retinal hemorrhages in the newborn infant has been reported to be between 2.6 and 50%. We postulate that the retinal hemorrhages are caused by maternal factors and fetal factors. Maternal factors include delivery type, maternal age, duration of pregnancy, parity, duration of labor, and maternal blood pressure. Fetal factors include color of the amnionic fluid, body weight, and sex. We examined the fundus of 161 newborn infants and investigated the above factors that influenced the retinal hemorrhages. The results were as follows: 1. The overall incidence of the retinal hemorrhages were 35.4%. 2. According to the delivery types, retinal hemorrhages were found in 57.9% after vacuum extraction, in 41.7% after induction delivery, in 33.8% after spontaneous delivery, and in 13.5% after Cesarean section. 3. As the duration of pregnancy increased in complicated delivery, retinal hemorrhages also tendted to increase. 4. The incidence of hemorrhages were greater in the hypertensive mother and abnormal color of amnionic fluid in spontaneous delivery. 5. The incidence of retinal hemorrhages were greater in the high body weight, multipara, and normal duration of labor. 6. Retinal hemorrhages were not related the maternal age and fetal sex. 7. Retinal hemorrhages were absorbed within four weeks.

Esophageal duplication is the congenital developmental anomaly manifestated as cystic or tubular type. The tubular esophageal duplication found at adult is extremely rare. A patient with tubular esophageal duplication is reported. A 37 years old male developed epigastric pain aggravated at hunger state from 2 monthes before administration. Gastrofiberscopy was done, and we could found the tubular esophageal duplication at 25 cm from incisiors. Esophagogram exposed the tunnel communicated with right anterior side of normal esophagus at upper and lower part of the tubular pathway with the length of 6 cm at T4-5 level. The microscopic finding of the tubular lumen revealed normal esophageal wall structure involving the outer part of muscle layer. Surgical resection was not done for the lesion was small and no symptom due to esophageal duplication was present. And so, the authors report this case as a tubular esophageal duplication with a literature review.
